Improvement in steam, water, and gas cocks



UNITED STATES PATENT OFFICE.

JOHN P. CONNELL, OF KENSINGTON, CONNECTICUT.

IMPROVEMENT IN STEAM, WATER, AND GAS COCKS.

Specification forming part of Letters Patent No. 147,240, dated February 10, 1874; application filed December 30, 1872.

T0 all whom it may concern:

Be it known that I, J OHN P. CONNELL, of Kensington, Hartford county, Connecticut, have invented an Improved Globe-Valve, of which the following is a specification, reference being had to the accompanying drawings, where- Figure 1 is a side view of the Whole valve. Fig. 2 is a view of the same in central vertical longitudinal section.

The letter a indicates the globular part of the valve; 1), the entrance-pipe; and c, the exit-pipe. d is the partition in which is the valve-seat d, facing toward the entrance-pipe. e is the valve proper, and f the valve-stem, having on its outer end the operating-Wheel 9. There is a screw-thread, f, on the stem f, taking into the nut or collar a', resting in a corresponding recess in the neck h, and held from turning by the pin 1" projecting from the nut and into a corresponding recess in the neck. The letter g indicates the stuffing'box, screwin g upon the neck h.

It will be observed that the neck h is solid, except the hole for the valve-stem, and can therefore be cast in one piece with the globe to and pipes b 0. Not only this, but the pressure of the fluid coming in at the pipe 1) tends to always close the valve into its seat and make it tight; and a valve thus made with solid neck h is not liable to explode by having the plug-screw driven out.

I claim as my invention- The neck h, solid except a hole for the valvestem, and made upon and in one piece with the body a, in combination with the threaded vah'e-stem f, the nut held from turning, and the stuffing-box g, all constructed, arranged, and designed for operation and use, substantially as described.

Dated October 13, 1873.

JOHN 1?. CONNELL.
